Wheel Change Jack Weighing
Place the airplane on the scales and place the jacks under the jacking points. Operate the
jack(s) to level the airplane and record the scale readings. Be sure to subtract the weight of the
jacks from the scale readings.
Locate the scale load points as described in the Wheel Weighing method that includes the
correction for the main gear bogie centerline. A correction for the jack locations must now be
made.
The nose wheel jack point is 0.35 ft (0.107 m) forward (-) of the nose wheel axle centerline and
the main wheel jack point is 0.28 ft (0.085 m) forward (-) of the main gear bogie centerline. The
main wheel jack point should be approximately at 2.5 ft (0.76 m) and the nose wheel at -18.7
ft (-5.70 m).
Remove the airplane and jacks from the scales and ensure that the scale readings have
returned to "0".
